Johansson talks 'Iron Man 2'

Scarlett Johansson has revealed the best part about playing Black Widow in Iron Man 2 was getting to "kick lots of ass".

Johansson is to star alongside Robert Downey Jr and Mickey Rourke in Jon Favreau's sequel to 2008's hit comic book adaptation.

When asked what she enjoyed most about playing a Soviet spy, the Lost in Translation star told SFX: "Kicking lots of ass. I wanted to give it everything I had.

"I hate to see a movie where you don't buy that a character is gonna beat the living s**t out of you. [Laughs] Believing that about yourself is almost as much work as looking like you could beat the s**t out of somebody."

Iron Man 2, from Marvel Studios, is due to arrive in cinemas and IMAX on May 7.
